Which federal agency enforces the ACAA?

The U.S. Department of Transportation (DOT) is the correct choice for the agency responsible for enforcing the Air Carrier Access Act (ACAA). The ACAA was enacted to ensure that individuals with disabilities have access to air travel and to establish rules that airlines must follow to provide assistance and accommodations for passengers with disabilities.

The DOT plays a crucial role in implementing regulations associated with the ACAA, which includes investigating complaints related to discrimination against individuals with disabilities in air travel. The Department also provides guidance and enforcement mechanisms to ensure that airlines comply with the law, thereby promoting accessibility and preventing discrimination.

Understanding the specific role of the DOT is important in grasping how the ACAA is enforced, as it outlines the agency's responsibilities and the mechanisms in place to protect the rights of disabled individuals in the context of air travel. Other agencies listed, while significant in their own domains, do not have the particular focus or authority granted to the DOT regarding the enforcement of the ACAA.
